The pop star was involved in a minor traffic accident late Saturday, but no one was injured, authorities said.
Spears was driving her 2008 Mercedes on the eastbound Ventura (101) Freeway just east of the 405 freeway about 8:20 p.m., said California Highway Patrol Officer Patrick Kimball.
Spears was in stop-and-go traffic when her car struck a 2006 Nissan in front of her that had stopped. The Nissan then pushed forward into another vehicle. No damage was noted to any of the vehicles.
The CHP took a report and no one was cited.
An after-hours e-mail sent to Spears' publicist was not returned early Sunday.
In 2006, Spears was photographed driving with her son on her lap.
A misdemeanor hit-and-run charge from an August 2007 parking lot crash was dismissed after she paid an undisclosed amount to the car's owner.
